Abstract
Measurements of GPS STEC carried out at Hainan station, are used to derive vertical total electron content (VTEC). The ionospheric variability of TEC for different seasons is discussed; GPS TEC is compared with the NeQuick model. We have found that the diurnal variation of TEC for different seasons shows the winter anomaly and semiannual anomaly; in general the diurnal maximum is the highest in equinox months, the least in summer months; The TEC of NeQuick model underestimates the TEC during night-time and overestimates it during daytime independent of the season.
